Safety Rules
• Incorrect wiring of this product may damage it and cause other hazards.
• The product must be installed by a qualified professional.
• Make sure the product has been wired correctly before turning on the power.
• Before wiring, removing, or mounting the product, be sure to turn off the power. Failure to do so may result in electric shock.
• Do not touch electrically connected parts, such as power terminals. Doing so may result in electric shock.
• Do not disassemble the product. Doing so may result in electric shock or malfunction.
• Use the product within the operating ranges recommended in the specifications (temperature, humidity, voltage, shock, mounting
direction, atmosphere, etc.) Failure to do so may result in fire or malfunction.
• Tighten the electrical wires on the connector. Insufficient tightening of the wires on the terminal may cause a fire.
• Disconnect the power supply before installation or maintenance to avoid electric shock or property damage.
• Use only copper conductors. Make all connections in accordance with local, state, and national electrical codes.
• To reduce the risk of fire or electric shock, install the equipment in a controlled environment relatively free of contaminants.
• This equipment is intended for use as a monitoring and control device only. To avoid loss of data or damage to the equipment, do
not use it for any other purpose.
• The cover or front panel of the Hub should not be removed. No configuration or maintenance action of the components (e.g. jump-
ers or battery) by the user requires the removal of the cover; all elements are accessible as connectors on the top, bottom, and side
of the Hub.
• The Hub must be mounted on a DIN rail in a cabinet or in an electrical box.
• When the Hub is mounted inside an enclosure, make sure the enclosure is designed to maintain the required operating temperature
range (allowing for 24 watts of dissipation by the controller). This is especially important if the Box is mounted inside an enclosure
with other heat-producing equipment.
• This product is intended for indoor use only.
• Do not install the Hub in an area:
- Where there is excessive moisture, corrosive fumes, or explosive vapours
- Where vibration or shock is likely to occur,
- Subject to electrical noise, e.g. near large electrical contractors, electrical machinery, welding equipment, etc.
• This equipment is not suitable for use in areas where children may be present.
• The Hub is not compatible with a Power-Over-Ethernet (POE) network. Connecting the Hub to a network segment carrying power
may cause a failure. In this case, you must disconnect the Hub from the POE network segment, turn it off and on again.
• To avoid any risk of injury caused by a fall, the Hub should not be installed more than 2 meters from the ground.
EN 60730-1 Power supply considerations
• Electrical safety in building automation and control systems relies primarily on the use of extra-low voltage, strictly separated from
the mains voltage.
This low voltage is either SELV or PELV, according to EN 60730-1.
• Protection against electric shocks is ensured by the following measures:
- Voltage limitation (low voltage supply 24Vdc DC ±10%, SELV or PELV),
- Protective separation of the SELV system from all circuits other than SELV and PELV,
- Simple separation of the SELV system from other SELV systems, PELV systems and the ground.
• Field devices such as sensors, status contractors, or actuators connected to the low voltage inputs and outputs of the I/O modules
must comply with SELV or PELV requirements. Interfaces to field devices and other systems must also comply with SELV or PELV
requirements.
• When power for SELV or PELV circuits is obtained from higher voltage power systems, it shall be provided by a safety transformer
or converter designed for continuous operation to power the SELV or PELV circuits.
